My favorite part of the game was the evolving music. That was the carrot I needed to finish the game. I wanted to know how the next part would sound like, and boy, it just got better and better. I like that you don’t have to collect 100% of the scraps, but just enough to get the bridge fixed. Especially for the last levels, because it became moderately more difficult for each level. I like how you “teach” the player about the mechanics without punching a tutorial into the the player’s face. I also did not know 2D and 3D could work so well together. And also, the most important part of the game, which I think you did very well, was the character controls. It was fun just running and jumping with the character.
The only thing that I think could be improved upon is a better visual of where the scraps and fuel are located. I mean, since they don’t reflect light the same way a 3D cubes does, it is difficult to accurately pin point where they are. The scraps with shadow on the ground made it at lot easier, and I know you can’t really have shadow on the scraps when they are floating in space, so it is difficult to improve. I also think it would be nice to start the jetpack by holding down the button from the first jump, without having to press a second time.
I really liked this game, five stars on everything from me. Good job!
